Patented Nov. l0, 1953 DOOR CONTROL MEOHANISM Edwin L. Allen, ClevelandHeights, Ohio, iassignor, by mesne assignments, to Rudolph I.Schonitzer,

Cleveland lOhio Application May 7, 1947, `Serial No. 746,521

"This invention pertains to :door control mechanisms and moreparticularly to apparatus for effecting and controlling the latching, orlatching and locking, of doors of the type commonly used on automotivevehicles.

In the Rudolph I. Schonitzer United `States Patents Nos. 2,694,413 and2,156,874, which issued on `September 28, 1937 and May 2, 1939respectively, certain door control mechanisms are described and claimed.The present invention relates to improvements in this general class ofdoor control apparatus.

This type door control mechanisms may be broadly described ashavingcoacting elements associated withlthe door and door frame structureswhereby the door may be latched1 and held in closed position or releasedfrom closed position to permit opening thereof, and as `including meanswhereby one of these coacting elements is retained in operative or doorlatched position when the door is closed and, when the mechanism isactuated to permit opening of the door, is moved into operated or doorunlatched position bymeans of a power element such as a spring or thelike.

My pending United lStates patent application Serial No. 713,220 filedNovember 30, 1946, and the Edwin L. Allen, `Angelo R. DeVito, and HaroldB. Muster pending United States patent application Serial No. 723,330,filed January 21, 1947, now Patent No. 2,587,583 issued March 4, `1952,disclose but do not claim certain features which are described andclaimed herein and reference is hereby made to said co-pending patentapplications.

Modern automobile body design requires that door latching and lockingmechanisms which are used to control the vehicle doors occupy a minimumof space in order that the mechanisms may be incorporated in the doors,and/or the adjacent body pillar structures, without interfering withtheraising andlowering of the window glass and without requiring anundesirable increase in thewidth of thedoor lock pillars or'windowframes. Automobile door control mechanism must also, of course, beextremely rugged and fool-proof and afford means lfor positively holdingthe door closed under most severe operating conditions. It is alsodesirable that means be incorporated in or'associated with automobiledoor control mechanisms whereby one or more of the vehicle` doors can belocked against unauthorized 3 openingthereof and suchtlockingmeansshould be operable either from ins-ideor outside of the vehicle. l

5 Claims. l (Cl. 292--216) Accordingly, among the objects of my `presentinvention is the provision, inra doorV control mechanism having alocking or restraining member for preventing release ofthe mechanismfrom operative or door latched position, of inside and outside actuatingmeans for the restraining member, eachof whichactuating means is at alltimes fully operable to movetthe restraining member into or out of itsrestraining position.

`Other objects of my invention include the provision of a door controlmechanism, particularly suited for automotive vehicle doors but notlimited to use therewith, `whereby it is impossible to close and lockthe door in questionfrom outside the vehicle except by use of a properkey or other locking device; the provision in a door control mechanismof remote control operating means therefor which may be installed in aplurality of positions remote from the control mechanism proper bymerely reversing the position of one of the parts of the mechanism; theprovision in a door control mechanism of means for operativelyassociating inside and outside actuating elements with a latch lockingor restraining member whereby either of said inside or outside actuatingelements may be operated to move the restraining member into or out ofrestraining position regardless of the position in which the restrainingmember may have previously been set by the other actuating element; theprovision of a door control mechanism for automobile doors cr the likewhich occupies a minimum of space and in which the moving parts areeffectively protected from undesirable matter such as dirt, sprayedpaint, ice, etc., and undesirable engagement with structural oroperating elements, such as the glass run channel, etc., which mightinterfere with the proper functioning of the door control mechanism; theprovision of a door control mechanismiwhich may be installed to beoperated to release and permit opening of the door either by push buttonactuated means or other type of elements such as handles, levers, ete.;the provision of a door control mechanism for automobile doors or thelike which facilitates installation with substantialspacing between thelatch member and the outside operating handle or push button, thuspermitting convenient operation while retaining the most effective latchlocation; and the provision of an improved compact, rugged, doorcontrolmechanism which is particularly susceptible to easy installation andeconomic-al manufacture. i

The above and` other objects of my invention will appearfrom thefollowing description `of sevnormal closed position.

Furthermore, although I have disclosed herein an arrangement wherein themovable latch member and its associated parts are carried by the doorand the stationary keeper member is carried bythe door frame it will beunderstood this arrangement may be reversed. So also the illustratedmovable bifurcated latch member .which Y coacts with a stationary keeperpin may be re- Y versed or interchanged so that the latch memberincludes a pin and the stationary keeper is of bifurcated or slottedform. Accordingly, the V`phrase latch member is used in this specicationandV the accompanying claims as a broad descriptive term and is notintended to be restricted to the pivoted bifurcated latch member whichis particularly shown and described herein.

InrFigures 1 and Y2 I have illustrated my improved door controlmechanism as installed in the left-hand front door Vof an automobile,the door being hinged at its forward edge and adapted to close againstthe body lock pillar (not shown in Figures l and 2 but seen infragmentary vertical cross section in Figure 5). The. door E has theusual outer panel land inner panel 2 and the free edge wall 3 closes therear edge of the door structure and formsthe outer wall oi the door lockpillar 5. Suitable means, not shown, are provided for raising andlowering thawindoW glass 5, the lowered position'of Vwhich isindicated'in phantom lines.

As is best seen in Figures toldV inclusive, the housing H of the doorcontrol mechanism installed in the door of Figures 1 and `2` includes Vabase plate I lforming'one side Wall of thehousing and adapted to 'be'held against the innersurfac'e ofthe door free `edge Wall 3 by thelscrews 6 en-` seeing threaded holes 6' in the plate fLand a `coverplate 8 extendinggener'ally parallel to and spaced from the baseplate 1. Integrally formed end Walls aand Il) extendwfrom the coverplate 8 and are secured 'to the base plate 'I as by bent Aover tangs orlugs II andi?. One edge of the housing H is substantially closed by theedge Wall or side flange I3 which may conveniently be formed integrallyvvvith the base plate, l and which, as will appear more fully later,projects somewhat 'beyond thecover plate 8 and supports the latchrestraining or locking means and the actu-` ating members therefor.

Extending through'and having suitable `bearing in the b ase plate 1 isthe latch shaft I4 (see FiguresS to 5). The latchyrnember L is securedto the outer Yend of shaft It` and, in the illustrated form of myinvention, is `bifurcated*to form a pair of spaced portions I5 and Itwhich maybe termed, in accordance with their primary functionsjthe latch`arm and door throwout and/or latch cooking arm` respectively.

This latter `position of my tripper typelatch mechanism may beterrned the "ipperatedi or door urilatchedposition.

Figure l5"illustratesfirlfull lines therelativepositions of the -latch member L and the keeper K when the door isclosed and in phant'ornlinesthe position pf the latch member L vvherithedoor is partially open and the `door controlrnechanisrrr is" in operatedor door unlatched position. "ln order -constantly to urge thedetent ljinto position` toholdthe control element I I -in operative or doorlatched position, as seen in liigure 3; a spring 2 5 is supported at itslower end by' the, bottcm 'end Wall-lt and has its upperend 25' pressingagainst the side o f the abutmentZS of .detent D. The spring 25 alsoengages the edge Wall i3 in order to sivo tho .desired Spring e0.-tion.` A slot in the edge Wall I3 permits the mid-portion of spring 2,5to extend thereinto and to be guided against lateral displacement.

From the above description it will be seen that the detent D isConstantly urged about its Apivotal support 2| in counterclockwisedirection (as seen in Figure 3) by the .Spring 25 'While'th latchcontrol element Il is constantly urged infelock'f wise direction aboutits pivotal support I4 by the Spring .|18. Whenthe parts are in operatedor door unlatched position `as seen in Figure 4 and the door is movedinto closed positionthe arm portion IE of the latch member IL strikesthe keeper pin K causing the latch L, shaft I4 and. control element Ilto move in counterclock- Wise direction. `During this movement thespring` I8` is being Wound up or tensioned and when the door reachesfully closed position the control element I1 vhas been movedsufficiently in counterclockwise direction to permit the abutment `2 3ofthe detent D to slide over the face of trie abutment 22 o f the controlelement l1 im@ the operative or door latched position` shovvny in Figure`2 3.

lease of the control element l1 and permit movement thereof, togetherwith the latch L, from operative or door latched position into operatedor door-unlatched position I provide a detent control member hereinillustrated in the form a of an arm generally indicated at 29 andpivotally mounted at its lower end on Va pin carried by the housing H.The inner edge 3| of control arm 2S is bent over` to form a detentengaging Vface 32 which operatively engages the cam face 33 of detent D.Movement of arm 29 about its pivotal support Si) is limited by a pin 34whichV is supported by the base plate 1, extends through aslot in arm29, and has a head portion 3S which assistsA in guiding and supportingthe arm 29 by maintaining the boss 31 (see Figure 11) insliding'engagement with the inner face of baserplate 1. Y

In Figure 3 the arm 29 is in its operative or door latched position withpin 34 engaging the left-hand end of slot 35. As detent D is urged incounterclockwise direction by spring 25V the arm 29 is urged inclockwise direction due to engagement of its detent engaging face 32with thecam face 33 of detent D. Movement of both detent D and arm 29under the inuence of spring 25 is limited however by the pin 34 which isso positioned relative to slot 35 that a positive stop is providedwhenthe detent abutment V23Y is in proper latchblocking position asshown in Figure 3.

A llange 33 is formed on the outer edge of Varin 29 and is adapted tovbe engaged bythe operating plunger 39 ofthe outside latchy operatingunit rBand it will be observed that,V when the parts of my door controlmechanism are in operative or door latched position as seen in Figure 3,and inward pressure is-exerted on the upper end of the detent controlarm 29, the resulting inward movement of arm 29 will cause detent inclockwise direction against the Vpressure ofV spring 25. This movementwill cause the detent abutment 23 tomove away from'the con- Y trolelement abutment 22 permitting the spring i8 immediately to rotate thecontrol element l1 in clockwise direction until the stop 21 strikes theboss 28 on the base platel 8. Of courserthis movement of the controlelement I1 causes similar movement of the shaft i4 and latch member Lfrom operative or door latched position as Ylatched position and is asillustrated in Figures 3 and Vl5 and the other may be ltermed, the`secondary operative or latched'positionY in which the door is notentirelyclosed Vand thel latch member L is in the ,position shown inFigure lr6.' VTo accomplish this secondary latching action Y I provide asecondary abutment 40 Von the control element I1 which is radiallyspaced from V.the full latched abutmentV 22. vA cam surface 4l lextendsbetween the secondary abutment 40 Vand the main abutment 22 and anothercam surface i12 extends away from the secondary By referring to Figure 4Yit willV the detent engaging face 32 thereof to act upon the cam face33 of the detent D to rotate the the parts are in operated or doorunlatched position and is held thereagainst by the spring 25. WhenV thedoor is moved toward closed position engagement of the arm I6 with thekeeper pin K causes the movable latch member L and control element l1 tomove in counterclockwise direction and the lower corner of detentabutment 23 will slide along the cam face 42 until it reaches thesecondary abutment 40 when it will move down into engagement therewith.`

Thus if Ythe door should not be fully closed it will nevertheless beheld in its secondary latched position by myrcontrol mechanism. As thedoor continues to move in closing direction beyond the secondary latchedposition and the latch control element l1 continues to'rotate incounterclockwise direction,V the lower cornerof detent abutment 23 willbe cammed outwardly by the cam surface 4I until it reaches the Ycornerof the control element abutment 22 whereupon it is snapped into fulllatched position by the spring 25 as is seen in Figure 3. It .will Vbeunderstood that in normal operation of the door the mechanism movesthrough Ythe secondary latch position Without hesitation and that if thesecondary latch arrangement is 'not desired it is only necessary to omitthe secondary abutment Iii! and continue the cam surface42 Vto thecorner or outer edge of the control element abutment 22. Y

The portions of my door control mechanism which have been described indetail up to this point in this specification provide means, operablefrom the outer side of Vthe door, for latching and unlatching the door.It is also, of course, usually desirable to provide means for operatingthe latch mechanism from theinner side of theY rotation of the detent Duntil the abutment 23 Y is moved out of engagement with the abutment2-2. plished entirely independently of the detent control leverV 29 andthus provides a second control means for, the release of the latchmember LV from its operative or door latchedV position. VAs the insidelatchroperating unit B (Figure 1) is j usually located away from theedge ofthe door 43.V This shaft 45, as is best seen in Figurefl,Vextends between'and generally Vparallel to the,

be seenV that the lower'corner of the detent Dfan operating member suchas a shaft 46 is provided having a flattened end portion 41 (Figure 5)operatively engaged in one ofthe angularly spaced slots 43 orr43 in thehub 440i pawl outer and inner door panels lV and 2 to the inside remotecontrollateh operating assembly B; This type of remote control assemblyis illus-V trated in detail in ,Figure 23 and includes a`downwardlyextending arm '5D secured to the shaft 46 and normally urgedtoward the inner doorpanel (in counterclockwise direction as seen inFigure 23)by a spring 5l which is supported by the stationary framemember 5l. The push button 52, or other suitable actuating element, isheld inpostion on the inner panel 2 of the This movement of pawl 43 maybe accom-` door byv a suitable escutcheon 53 mounted` on frame 51"- asby a bayonet joint,` and itwill be seen that inwardpressure on thebutton``2 will cause corresponding rotary movement of the shaft 46S Thismovement of shaft 46 is trans-` mitted to the' paw'l 43 causingrotationthereof in counterclo'ckwise direction as seen in Figure 3 thus"releasing the latch mechanism and `permitting the latchmember' L tomove into op eratedl or door unlatched'position.

In the'installations `of my4 door control mechn anism shown in Fguresland 19 the` inside latch releasing push button is located below theshaft 46`and at a relatively great' distance below the lower, edge ofthewindow frame.` However, in some` cases it 'isdesired tolocate the pushbutton or other operating means higher Aon the door paneLj can readily`be vaccor'nplished by merely locatingthe push' button 52 above theshaft1 4&5 and changingftheangular position of the pawl43 duringassembl'yof the vdevice from that shown'ln full lines ,nFigure Sito thatshown' in'dot and dash lines in Figure?,Y and in full lines 'in Figure3a; wWhen so assembled the face 43 of the pawl 43 `will en 'gagetheupper end of y,the inner edge 3|" of @the detent control arm 29.` Itwillbe understood that when the push button 52'i`s disposed iabove the shaft46 inward movement thereof will cause the shaft 46`to move in theopposite direction from that caused by movement of the push button whenassembled below the shaft 46. This opposite rotation of the shaft 46`(clockwise as seen in Figure 3) will cause the face 43 of the pawl 43to move the detent control 4arm `29 `counterclockwise or releasingldirection and such"movement will' effeet release of the latch member Lin thesar'ne manner as' thoughthearm 29had been" moved byoperation' ofthe outside 4operating assembly B. By` providing the slots 48" and '49in the hub 44l of pawl 43- the pawl may be assembled Vin either of thetwo positions whichhavebeeh de# scribed above, which positions intheillustrated embodiment are approximately 90 apart, and in either caseone of thel slots v43 or'49`will be substantially vertically disposed,thus 'permitting the flattened`endt41 of shaft 46 :to be operativelyconnectedto the pawl 43 in the same relative position regardless ofwhich arrangement is employed` Itwill be Vunderstood that instead offorming intersecting angularlyl spaced slots in thehub 440i pawl 43as'shown at 48 and 49, separate Yangularly disposed slots might beernployed, or the aperture inf-the hub yll4co`1ildbe of -any otherAnon#circular"firL'the' end of Shaft 46`bei'ng properly Shaped to ttherein lin-a plurality of positions. t t A The window glass 5, as? isfclearly'seen in"i'ig ures 5 `and 7, is guidedand supported at its edgesby the usual'glass run channels, one of which is indicated at`f4. Indesigninganautomobile door it` is'l usuallyndesirable to locate theV,glass run channel V54 as close as'ipossible to thenfr'ee edge wall 3so thattheswidth of the pillar `4 may be reduced to a minimum, thusobtaining maxi'- mumvsibility from within the"vehicle.` In theillustrated doorassembly the glass run` channel 54fis` 'located"immediately adjacent the cover plate"8of the doorfcontrol mechanismhousing H.

When urged in latch releasing direction-the stop face tit oidetent D engages the lower edge et ofrestraining member R and exerts aiorceor pressure thereagainst in a direction which is substantiallyparallel to the'plane of movement of member R and normal to the axis ofthe pivotal support pin 55. This relation permits the angle between edgewall I3 and base plate I to be varied-from that illustrated through asubstantial range, to fit various door bevels or installationrequirements, without interfering in any way with the operation of therestraining member R or requiring any change in theform or mounting ofeither detent D or restraining member R.

' The unlocked or latch released position of the restraining member R isshown in Figures 4 and 6, it being noted in Figure 6 that the member Rhas been moved in clockwise direction on its pivotal support 55 untilthe upwardly extendingportion 6G strikes the stop member Si which isbent inwardly from the edge wall I3. In this position the detentblocking end 56 is moved comdoor structure and is provided with anoperating knob or the like S4 at its upperv end. VFigures 3, 4, 5 andlillustrate the manner in which the lower end of actuating rod e2 isoperatively connected to the restraining member R. A hole is formed inthe upper Vportion Si) of member R to accommodate the inwardly bent endSie or" rod si. When in operating position the lower inner side of rod62 extends parallel tov and adjacent the face of end portions@ while theopposite side of rod-62 is yparallel-to and guided by the projecpletelyout of the path of the detent block arm 58, thus permitting normaloperation of the control mechanism as has been previously described. Inorder to hold the restraining member R in either its released positionas seen in Figure 6 or in its restraining position as seen in Figure 5 Iprovide a toggle or snap-over spring 55a which is of coil form and isdisposed between the member R and the edge wall I3. One end, 55h ofspring 55a is anchored to the edge wall I3 and the other end 5F26extends into and is anchored in the restraining member R. When themember RV isY in released position as seen in Figure 6 the end e5 ofspring 55a is located above the common center line of pivot pin 55 andthe xed end 55h of spring 55e. During movement of restraining member Rfrom released position into restraining position, as seen in Figure 5,the end 55C of spring 55 moves across to a position below the commoncenter line of pin e5 and flxed end 55h of spring 558. This causes thesnap-over action to take place and, as illustrated herein, occurs afterthe forward edge of end 5E of restraining member R passes the inner iaceof detent D. Thus, spring 55a starts to urge restraining member R intoits released position just before the blocking end 55 completely movesout oi the path of detent D and starts to urge restraining member R intorestraining position just after end 56 rst enters into restrainingArelation with detent D. By this arrangement of snap-over spring 55a therestraining member R is maintained in either released position or inrestraining position and is not urged in restraining direction -by thespring 55a until after the blocking end 5t is at least partially indetent blocking relation to the detent D. It will be understood thatother types of toggle or snap-over spring mechanisms may be employed tocarry out the functions of spring 55a.

To permit operation of the restraining member R from inside of the doorI have provided actuating means indicated generally at A in Figure 1 andcomprising an actuating rod 62 which extends up through a suitablegrommet $3 in the tion its of the edgewall I3 of housing I-I. Thus therod 62 is guided by the members Sand 43a and the bent end portion 52a isheld Vin position in thehole in the upper. end Si) oi the restrainingmember R. Installationv of the rod 62 is easily effectedwhen therestrainingmember R is in locking position asV seenin Figure 5 by mereiyholding the rod 62 substantialiy atV right-angles to its normaloperating position and inserting the end a in the hole-in the upperportion i@ oi restraining member R. This can be accomplished because, asis evident from Figure 5, the upper end Ita of the edge wall |3- is cutaway to provide access to the hole when the member R is in restrainingposition. The rod 62 is then swung into its vertical or operatingvposition between the members 6i) and i321. By properly spacing thesemembers a rattle-proof,V simple and easily asserzibled operatingconnection is provided between the rod E2 and the restraining member R.Screws, rivets or other securing devices'are completely eliminated withcorresponding reduction in cost and assembly time.

Movement ofl the knob 64 from its upper or unlocked position as seenr inFigures 4 and 6 into its lower or locked position asseen in Figures 3'and 5 will move the restraining member' R into blocking position toprevent latch releasing movement'of the detent D. This movement oftheVrestraining member R, however, can occur only the detent lock arm 5Shas moved upwardly into the" path ofthe end 56 of restraining member Rso that if the knob 5e is moved downwardly the restraining member R maybe rotated in locking direction only until the end 'strikes the innerside face of the detent lock arm 58. Thus the latch restraining meanswhich I have incorporated in my door control mechanism is operable toprevent release of the latch mechanism only when the latch is in itsoperative or door latched position. l y

In addition to the inside actua-ting means for the restraining member Rwhich has just been described it is, oi course, desirabie to providemeans for operating the locking or restraining member 'R from theopposite side of the door D. In order to accomplish this, and to combinethe latch restraining means which is incorporated in my controlmechanism with a key controlled lock, I provide means for operatively.associating the restraining member R with the outside key controlledactuating unit which has generally been referred to at A' in Figure 1.Connecting link 65 is pivotally secured at its upper end to therestraining member R and extends downwardly adjacent and generallyparallel to the edge wall i3 of the housing H. At its lower end the linke5 is slotted at B6 to provide Va limited lost
